A striking new design of electricity pylon can be seen in the english countryside for the first time.
National Grid has begun construction of a line of the new high voltage T-pylons, which at 35 metres are up to a third lower in height than the traditional steel lattice pylons.
The pylon was the winner of an international competition to find a 21st century design for carrying high voltage overhead lines.
Its innovative but simple layout gives it a T-shaped cross arm, with the electricity wires and the insulators which hold them in place arranged in a diamond “earring” shape.
The T-Pylon is designed to have a reduced visual impact on the landscape: it has a smaller footprint than the traditional steel lattice pylon and is about a third lower in height than its skeletal forebears. It is also quicker to build: prefabricated in bolt-together sections, it can be assembled by a team of five people in a day, compared with the nine people working for five days required for the original design.
Six of the new pylons have been erected at the National Grid’s training academy in Eakring, Nottinghamshire, each demonstrating a different function in the network.
“I’m incredibly proud of the high standard of engineering that brought us to this point. We developed the new style of pylon so that we could have a 21st century design to offer as we plan new transmission routes.” – David Wright, Director of Electricity Transmission Asset Management, National Grid UK.
